NOT WORKING YET!
To use, create a folder called "io_scene_xsi3" in your blender addons folder. Extract the files into the new folder, open blender, and activate the addon in preferences. Look for "Softimage XSI 3.0 Export" in addons.
This addon is based off of the 'io_scene_bz2xsi' addon by frute94 which can be found here: https://github.com/frute94/io_scene_bz2xsi
Changes:
- Modified to export the standard XSI 3.0 format.
- Added export options for Jedi Outcast/Academy's "carcass" program.
